JPS5815225Y2 - Forward-facing muffler protection structure for mobile work vehicles - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a forward-facing muffler protection structure for a traveling work vehicle that protects the forward-facing muffler from tree branches and the like.

2. Description of the Related Art Some mobile working vehicles, such as tractors and management machines, have a so-called forward-facing muffler along the upper edge or side of the bonnet in order to work in greenhouses, greenhouses, orchards, etc.

This forward-facing muffler is installed with a slight gap between it and the bonnet (because it heats up, which adversely affects the paint on the bonnet, and causes relative vibrations and collisions with the bonnet). In some cases, tree branches or fruits may enter the gap and damage the muffler.

In view of these problems, the present invention provides a forward-facing muffler for a traveling work vehicle, which is configured such that an intruder removal member is provided in front of the forward-facing muffler to prevent intruders from entering the gap between the front-facing muffler and the bonnet. The purpose is to provide a protective structure.

The present invention provides a traveling work vehicle with a forward-facing muffler.
In order to prevent intruders from entering between the bonnet and the muffler, an intruder removing member is disposed in front of the muffler.

Embodiments of the present invention will be described below with reference to the drawings.

In the embodiment of the present invention shown in FIGS. 1 and 2, 1 is the front half of the agricultural tractor, 2 is the hood, 3 is the safety cover, 4 is the front wheel, and the forward-facing muffler 5 is the upper part of the bonnet 2. It is located along the left edge.

Reference numeral 7 denotes a cradle for the battery 8, which is fixed to a front wheel cradle 9, and a battery support 10 is fixed to this cradle 7.

Said bonnet 2 is bolted to the battery support 10 via fasteners 11.11 and bolts 12.

Reference numeral 13 indicates a radiator, and 14 indicates a top plate of the bonnet 2 that can be opened and closed.

Reference numeral 15 denotes a mounting member for mounting the muffler 5 in a forward facing position, which has a muffler fitting part 15a and a mounting part 15b, and a hole for inserting the bolt 12 is formed in the mounting part 15b.
Battery support 10 together with stopper 11 of bonnet 2
Fixed.

By aligning the mounting portion 15b with the bonnet 2, the mounting structure is simplified and the number of parts is reduced.
Moreover, the mounting portion is surrounded by a safety cover to improve the appearance.

The muffler fitting part 15a is made by cutting a part of the annular shape and tightening the part 15a.
C, and after fitting into the muffler 5, the tightening part 15
By fastening c with the bolts 16, the muffler 5 can be firmly fixed to the mounting member 15.

Reference numeral 20 denotes an intruder removal member formed of a bar material, and the attachment end 20
A is threaded and inserted into a cylindrical member 17 that is welded (or bolted) to a mounting member 15, and is fixed to the cylindrical member 17 with two nuts 18 and washers 19.

The removal member 20 can be adjusted in its relative position with the cylinder member 17 by loosening both nuts 18, that is, in its longitudinal position and angle with respect to the muffler 5, and can be used commonly for various models.

The exclusion member 20 extends forward along the muffler 5 from the mounting end 20a, slopes from the first bent portion 20b, crosses the front of the muffler 5 and the gap A, reaches the front of the bonnet 2, and extends forward from the second bent portion 20b.
It extends downward from the bent portion 20C.

The first bent part 20b to the tip 20d of the exclusion member 20 may be located on the same plane, but the second bent part 20C may be formed in a mountain shape that protrudes forward, so that tree branches, etc. It is more preferable to configure the branch to be removed upwardly when it comes into contact with the upper part of the second bending part 20C, and downwardly when it comes into contact with the lower part of the second bending part 20C. Also, the closer the branch is to the front of the bonnet, the greater the effect of removing the branch is. .

When a tree branch comes into contact with the exclusion member 20 while the tractor 1 is running, it is guided upwardly and outwardly or downwardly, and is prevented from invading a person.

Therefore, branches and nuts will not clog the gap, and the muffler 5
The connecting portion between the muffler 5 and the exhaust manifold (not shown) and the mounting member 15 are less likely to be damaged by branches or the like.

3 to 6 show four examples of how to attach the exclusion member, and in FIG. 3, the attachment end 20a is formed into a flat shape and the attachment portion 1 is
5b, and connect the first bent part 20b to the second bent part 20b.
tilt upward to the bent portion 20C, and the second bent portion 20C
It hangs down from the tip to the tip 20d.

Fig. 4 shows an example in which the muffler fitting part 15a of the mounting member 15 is shaped into two halves, and the flat mounting end 20a is collinear with the connecting part 25 of the two halves located on the outside with bolts. The arrangement and shape of the exclusion member 20 are substantially the same as those of the previous embodiment.

In the example shown in FIG. 5, the mounting end 20a (no screws are formed) of the exclusion member 20 is attached to the mounting member 28 via the mounting bracket 26, and the mounting bracket 26 is connected via four bolts 27. It is fixed to the mounting member 28, and by loosening the bolt 27, the amount of forward protrusion of the removal member 20 and the bending portion 20 can be changed.
The direction of inclination from b to tip 20d can be changed.

The muffler fitting part 28a of the mounting member 28 is annular with no notch, while the muffler 29 is formed with a flange 29a and a threaded part 29b, so that the muffler fitting part 28a is brought into contact with the flange 29a. After fitting the muffler 29a to the muffler 29a, the nut 30 is screwed onto the threaded portion 29b.
is fixed to the mounting member 28.

FIG. 6 shows an example in which the exclusion member 32 is attached to the front side of the bonnet 2, and the mounting bracket 33
The mounting part 32a fixed to the first bending part 32
The fastening bolt 3 of the mounting bracket 33 has a linear part 32c projecting forward from the straight part 32c, and a removal part 32f extending upwardly and outwardly from the second bent part 32d to the tip part 32e.
4, the linear part 32c becomes rotatable around the attachment part 32a, and the position of the exclusion part 32f outward from the bonnet 2 can be adjusted, and the exclusion member 32 can also be adjusted up and down.

It is preferable to remove the tree branches that come to the tips of the muffler 5 and the bonnet 2 so as to flow backwards and upwards so as not to damage them. Also, the removal member 20 is made of a plate instead of a bar and is removed from the muffler. 5 and the front of the gap A may be shielded.

In the present invention constructed as described above, an intruder exclusion member is provided in front of the forward-facing muffler to prevent tree branches, nuts, etc. from entering between the muffler and the bonnet. It is possible to prevent damage to the muffler and the members near the muffler caused by objects, and by configuring the front and rear positions and angles of the removal member to be freely adjustable as in the embodiment, it can be used for many models, and can be used to remove branches, etc. Can be eliminated efficiently.
